Description

Technical Field

[0001] The present application relates to the technical field of aviation engine parts manufacturing, and in particular, to a wax filling device for aviation parts. In addition, the present application also relates to a wax filling method including the above-mentioned wax filling device for aviation parts. Background Art

[0002] The information provided in this section is for the purpose of generally presenting the background of the present application. To the extent described in this section, the work of the presently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly admitted to be prior art to the present application.

[0003] In the processing of aircraft engine parts, the prevention and control of waste is an important process and a key quality process. Before the machining process, in order to prevent waste such as iron filings from entering the pipes and cavities of parts, the common prevention and control method at this stage is wax filling. The method is to first heat and melt the solid wax block in a metal container, and then use the container to fill the liquid wax into the pipes and cavities that need to be sealed with wax. Please refer to the attached manual. Figure 7 and 8 .

[0004] After research, we found that: during the pipeline wax sealing process, due to the lack of pressurized injection, there will be insufficient sealing, and during the mechanical processing, the wax will fall off, causing iron filings to enter the pipeline;

[0005] In addition, a large amount of liquid wax is required when filling a larger cavity. The existing container volume is limited, and sometimes it needs to be heated multiple times. A long time interval between two wax injections may lead to insufficient cooling and may fall off during processing, thus affecting product quality.

[0006] In addition, since the existing methods all use traditional simple tools and open space operations, there are pollution such as smoke, pungent odors, and excess wax droplets scattered in the workplace during the process, so there are also problems such as not being energy-saving and not being environmentally friendly.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0046] The present application discloses an aviation component wax filling device that temporarily stores wax blocks through a feeding trough 1, and conveys the wax blocks to a heating trough 4 through a spiral conveying pipe 3.

[0052] It can be understood that the heating tank 4 can control the temperature of the wax liquid within the melting point range through the heating wire 41, and detect the real-time temperature of the wax liquid through the temperature sensor. If the temperature exceeds the limit, the heating wire 41 will be powered off to achieve temperature control of the wax liquid.

[0053] Optionally, the outlet of the heating tank 4 is connected to the wax injection pipe 6, and a filter is provided at the outlet of the heating tank 4 to prevent impurities from entering the pipeline and keep the wax liquid clean.

A storage turntable is provided in each pipe storage box 7, and the middle portion of each wax injection tube 6 is used to be wound on the storage turntable and the wax injection tube 6 can be wound and unwound through the storage turntable.

[0055] It is understandable that the storage turntable can retract the used wax injection tube 6 and wind it for storage. Preferably, the storage turntable adopts a spiral spring storage disk, which can realize the automatic retraction of the wax injection tube 6. Since the pipeline storage box 7 is arranged on the outer wall of the heating tank 4, it can keep the wax injection tube 6 warm and control the temperature in the melting point range of the wax, so as to realize the pipeline preheating of the wax injection tube 6, ensure that the wax in the pipeline is in a liquid state, and prevent the wax liquid from cooling and clogging the pipeline in advance.

At the same time, the exhaust fan 10 is used to extract air to improve the exhaust gas treatment capacity. The extracted gas is firstly filtered through the filter assembly 9 to reduce the impact of impurities on the exhaust fan 10, and then filtered through the clean water 12, and then the filtered gas is discharged, which effectively reduces the impact of smoke and irritating gases generated during the wax filling process on the workshop air environment, and ensures the respiratory health of workers.

The first mounting plates 95 on both sides are respectively connected to the filter mounting plate 93 at the first filter 91 and the filter mounting plate 93 at the second filter 92 through connecting members 94.

[0062] Preferably, the connecting member 94 is a plate-shaped structure made of elastic material. The density of the first filter screen 91 is less than the density of the second filter screen 92 .

When the wax filling operation is completed, when the filter assembly 9 does not need a strong filtering treatment, or in order to improve the efficiency of air extraction, the distance between the first filter 91 and the second filter 92 can be widened to increase the flow rate of the air in the intake pipe 85.

[0064] Preferably, the filter screen mounting plates 93 are connected by connecting bolts, and the spacing between the filter screen mounting plates 93 is adjusted by connecting nuts. The size of the filter chamber 97 can be adjusted to be more stably maintained in a fixed state.
